Return Value

The following example defines a custom NumberFormatInfo class that defines its negative sign as the string "~" and its positive sign as the string "!". It then calls the ToString(UInt32, IFormatProvider) method to convert an unsigned integer value to its equivalent string representation. The conversion uses both the invariant culture and the custom NumberFormatInfo object. The output indicates that this formatting information is not used, because by default the "G" format specifier does not include a positive sign with positive values.
